UNITED STATES PATENT OFFICE.

MATTHEW PARKER ISMAY, OF NEWCASTLE-UPON-TYNE, AND JOHN WALTON ROBINSON,OF HAYDON BRIDGE, ENGLAND.

APPARATUS FOR ROLLING MEAT AND LIKE SUBSTANCES.

To all whom it may concern Be it known that we, MATTHEW PARKER ISMAY andJOHN vVAn'roN ROBINSON, subjects of the King of England, residing,respectively, at Newcastle-upon-Tyne and Haydon Bridge, both in thecounty of Northumberland, in England, have invented certain new anduseful Improvements in Apparatus for Rolling Meat and Like Substances,of which the following is a specification.

This invention relates to improvements in apparatus for rolling meatsuch as hams, shoulders and sides of bacon, beef or the like, of thatclass, wherein the meat is rolled by a band formed of links andtraveling over rollers in the machine.

A certain amount of slack is provided in the band, the meat being rolledin the loop formed by this slack and which hangs be tween rollers, oneof which is adjustable relatively to the other to allow the introductioninto the loop of the meat to be rolled and to tighten the loop aroundthe meat, means being provided whereby as the meat becomes more compactthe band is kept tight around the same.

The present invention provides improved means for keeping the band tightaround the meat or other substance being rolled, these means beingoperated by pressure on a foot-- lever which at the same time operatesclutch mechanism for starting the machine. Im-

mediately the pressure on the foot lever is removed the clutch mechanismis automatically disengaged and the machine stops. The invention furtherconsists in im' proved means for guiding the adjustable roller, partlysupporting the loop toward or away from the driving roller to allow theinsertion of the meat and the initial tightening of the loop around thesame.

The invention further comprises minor details of construction as willhereinafter be described and specifically pointed out in the appendedclaims.

An embodiment of the machine is shown in the annexed drawings, in whichFigure 1 is a front elevation of the improved machine; Fig. 2 is apartial plan view of the same; Fig. 3 is a side elevation; Fig. 4 is asection on line AA of Fig. 1. Fig. 1 is a detail section takenapproximately on line A--A of Fig. 1, certain parts being omitted forclearness. Fig. 5

is a section on line BB of Fig. 1. Fig. 6 is a side elevation similar toFig. 3, and illustrates an alternative method of taking up the slack ofthe rolling band; Figs. 7, 8, 9, are details of construction of the bandon an enlarged scale.

Between the vertical sides or cheeks 2 of framing braced together bybars 3 at the back and bars 4 at the bottom, a number of horizontalrollers of suitable length and made of wood or other suitable materialare carried or supported. Of these rollers, the upper front roller 5 isthe driver, and is grooved or otherwise roughened to grip the band 6;its shaft 10 is carried in fixed bearings 11 on the frame.

7 is the upper back roller at a higher level than the front roller, andits spindle 17 is carried in bearings 18 adapted to slide in horizontalguides 19 bolted to or integral with the frame, the range of slideextending from a point where the two rollers 5 and 7 come comparativelyclose to each other back to a point which leaves a space between therollers suflicient to admit the largest sized piece of meat or the liketo be rolled. The forward ends of guides 19 are made solid as at 20 andact as stops for the bearings 18 which are provided with verticalextensions 21 joined by a horizontal plate 22 which serves as a shelf.The bearings 18 may be coupled together in any other suitable manner. Athird roller 8 is located below the roller 5, and its spindle 39 iscarried in bear ings 10 adapted to be moved up and down upon verticalrods 41 connected to a foot le'ver described hereinafter and fixed onsaid rods by set bolts 42, the vertical rods moving in guides 43 fixedto the frame; a fourth roller 9 is arranged toward. the back of themachine at a suitable level, and its spindle 44: is carried in fixedbearings on the frame. The endless band 6 of suitable material passesover all the rollers mentioned so that the same surface of the bandcomes against all said rollers. A certain amount of slack is provided inthe band for holding the meat and this slack falls down between theupper two rollers 5 and 7 and forms a loop in the band 6, in which loo-pis made to suit the size of meat to be rolled, and is regulated byadjusting the roller 8. The band may be constructed of bars of hard woodof tapered section placed paralthe meat is'rolled. The amount of slack Ilel and close to each other but not necessarily touching and the endsconnected by metallic links, but we may make the bars 57 of uniformsection as illustrated in Figs. 7 and 8 instead of tapered section. Theband passes over the upper two rollers 5 and 7 and under the lower tworollers 8 and 9.

The foot lever before referred to consists of two arms 31 inside of andpivoted at 32 to the respective side frames 2, a bar 33 joining the backends of said arms and another bar 34 joining the front ends thereof thesaid front bar 34 being provided with a strip 35 made of wood. Balanceweights 36 are placed on the rear end of the bar 33, and the band istightened during operation of the machine by pressing the foot on thefront member 35. On one end of the driving shaft 10, and outside theside frame bearing is a sprocket wheel 12 provided with inclined facesor teeth 13 (Fig. 2) to engage recesses in the face of the bearing. Abelt sheave 14 is mounted on shaft 10 and is driven by any suitablepower, the said sheave-being provided with teeth to engage a clutch 15of suitable type for coupling the belt. sheave. The sprocket wheel 12and the belt sheave 14 ride loosely on the shaft 10 and a helical spring16 is interposed between the clutch l5 and the belt sheave to keep theboss of the belt sheave pressed against the boss of the sprocket wheeland the latter against the face of the bearing. A chain 37 is connectedto the bars 34 of the foot lever and passes over the sprocket wheel 12,a balance weight 38 being attached to the other end of said chain. Whenthe sprocket wheel is turned by pressing the foot lever the said wheelis forced away from the bearing by means of the inclined faces. Thismoves the belt sheave 14 along the shaft 10, compresses the spring 16and the sheave engages with the clutch 15. As long as the pressure isexerted on the foot lever the machine will be working. Directly suchpressure is removed, the spring 16 throws the clutch 15 out of gear, andthe machine stops. A ratchet wheel 52 engaged by a pawl 53 mounted on across bar 49 is provided at one or both ends of the driving shaft 10 toprevent the roller 5 turning when the'machine is not working. Aforwardly projecting arm 23 is pivoted on pins 24 to each of thevertical extensions 21 of the sliding bearings 18 and the front ends ofsaid arms are joined by a bar or bolt 25, by means of which the roller 7can be moved backward or forward.

On one or both pivot pins 24, and on the insides of the extensions 21 ismounted a pawl 26 (one being shown) which engages a ratchet wheel 27fixed on the spindle 17. This pawl is lifted out of gear with theratchet wheel 27 by the action of a lever 28 mounted on the pin 24outside extension 21 and provided at its end with a roller 29 whichbears on the upper outer surface of bearing guide 19. This surface isinclined or raised as at 30 sufliciently to throw the pawl 26 out ofgear with the ratchet wheel 27.

31 is a downward projection on the arm 23 engaging in notches in theguide 19 to [ix the roller 7 is position. On thedrawing, notches for theforward position of the roller 7 only are shown, but may be provided forthe back or any other positions.

The means for stringing the meat after rolling consists of a screwthreaded bar 45 parallel to and in front of the driving shaft 10, anddriven by means of a toothed wheel 46 thereon from a toothed wheel 47 onthe driving shaft at a speed depending on the diameter of the roll ofmeat and the distance apart of the coils of string on said roll. Ahalf-nut 48 adapted to engage the screw threaded bar 45 is slidablymounted on a bar 49 parallel to and behind the bar 45. The nut 48 has avertical extension 50 around which one or more turns of string are takenafter the latter has been attached to the meat. Normally the half nutfalls out of engagement with the bar 45 and is put in engagement by theattendant pressing on the vertical extension 50. At the same time thestring is passing through his hand and he can easily adjust the pull onthe same.

51 is a stay bar which acts as a stop for the half nut 48 when out ofgear with the screw threaded bar 45.

54 is a plate for keeping the end of the meat flat while being rolledsaid plate being carried by stays 55 passing through one side frame 2.

56 is an aperture in the opposite side frame. The band 6 see Fig. 7, ismade of bars 57 of hard wood connected by links 58, 59 and screws 60.

Instead of adjusting the length of slack of the band by moving theroller 8 as direct ed above we may mount this roller in a suit ableposition and provide two additional rollers 61 and 62, Fig. 6, carriedon spindles on the ends of two levers 63 of suitable length, each leverbeing centrally mounted on pins 64, one 011 each side frame 2. This iseffected by arms 65 fixed on pins 64 outside each side frame and joinedby a bar 66. The levers 63 are kept in the required position by a pinengaging in a hole 67 in the lever 65 and in one of the holes 68 in sideframe 2. The greatest amount of slack in the band between the rollers 5and 7 is when the lever 63 is near the horizontal position and the arm65 in its raised position. The least amount of slack in the band is whenthe lever 63 is near the vertical as indicated by m and arm 65 in itslower position; the arrows in Figs. 3 and 6 indicate the direction oftravel of the band, which passes under the third roller 8 as before,over the first additional roller 61, under the second additional roller62, and around the back roller 9.

The action of the machine is as follows Before putting in the meat to berolled, the machine is stationary, the belt sheave 14 running loosely onits shaft. Roller 7 is in its rearmost position, and the slack band ishanging down between rollers 5 and 7. When the roller 7 is in the saidrearward position, and also in any other position but its foremost one,the pawl 26 is in engagement with the wheel'27, and the roller 7 isprevented from rotating. The driver roller 5 is also prevented fromrotating by the pawl 53 engaging the wheel 52. After fastening thestring to the thick end of the meat, the latter is doubledlongitudinally and placed in loop 6 of the band with the thick endpressed against the plate 54. The roller 7 is drawn forward to theposition shown in the drawings and the string is coiled once or twicearound projection 50 by the operator who lets the string run through hishand from the source of supply, and can control the tension on thestring at will. He then presses with his foot on the front member 35 ofthe foot lever, which action tightens the band, and at the same time bymeans of the chain 37 turns the wheel 12 through a certain angle whichby means of the inclined teeth 13 forces said wheel and the belt sheave14 along shaft 10 causing the sheave 14 to engage the clutch 15. Theband is thus put in motion and the meat rolled. The stringing is done bypressing the projection 50 to bring the nut 48 into mesh with the screw45, and it is held in mesh during the travel of the string from one endof the meat to the other. The

travel of the string is stopped by taking I until the inclined teeth 13cause the sheave.

14 to be thrown out of gear with clutch 15 by the spring 16. The roller7 is then thrust back and the meat lifted out.
